Fikir khaldan: "Baabuurta mishiinka naaftada leh waxa uu wasakheeyaa in ka badan baabuur wata mishiinka shidaalka."
Baabuurta naaftada ah waxay ka kooban yihiin ku dhawaad saddex meelood meel baabuurta Faransiiska ah. Rikoorka Yurub! Laakiin sannadihii la soo dhaafay, sida laga soo xigtay ganaaxa deegaanka iyo fadeexado ay ka mid yihiin Dieselgate, matoorada naaftada ayaan hadda caan ahayn. Laakiin waxaa jira ra'yi baahsan oo ku saabsan shidaalka naaftada: waxa ay wasakhayso in ka badan shidaalka, liddi ku ah, ka yar ... Vrumli deciphers kuwan clichés!
Run mise Been: "Gaariga injiinka naaftada wata ayaa wax ka badan ka wasakhoobay gaadhiga mishiinka shidaalka"?
RUN, laakiin...
Naaftada waxaa ku jira noocyo kala duwan oo wasakh ah: qaybo yaryar, ka dibna oxides nitrogen (NOx) iyo Qiiqa gaaska lagu sii daayo... Sida qaybaha yaryar, filtarrada particulate (DPF) hadda waxaa lagu rakibay matoor cusub oo naafto ah. DPF waa lama huraan, laakiin gawaarida faransiiska waa da' oo wali waxaa ku jira baabuur badan oo naafto ah oo aan lahayn filtarrada.
Dhanka kale, injiinka naaftada ah waxa uu sii daayaa gaasaska aqalka dhirta lagu koriyo oo ka yar baabuurta shidaalka. Matoorka naaftada ayaa ku wareegsan % ee 10 CO2 in ka yar In ka badan matoor shidaal! Dhanka kale, shidaalka naaftada ayaa dhab ahaantii sii daaya NOx aad uga badan baabuurka shidaalka. Sababtan awgeed, shidaalka naaftada ayaa loo arkaa inuu ka wasakh badan yahay shidaalka.
Dhab ahaantii, gubista shidaalka naaftada, la mid ma aha kan shidaalka. Sababtaas awgeed, iyo gaar ahaan hawada xad-dhaafka ah ee ay tani tilmaamayso, shidaalka naaftada ayaa soo saara oksijiin badan oo nitrogen ah inkastoo horumarka tignoolajiyada sanadihii ugu dambeeyay.
Haddaba, gaadhiga naaftada ah waxa uu sii daayaa NOx laba jibaar ka badan baabuurka shidaalka. Si kastaba ha ahaatee, oksaydhyada nitrogen ayaa gacan ka geysta saamaynta aqalka dhirta lagu koriyo iyo ku dhawaad 40 jeer ka badan oo sun ah marka loo eego carbon monoxide.
Dalka Faransiiska, baabuurta naaftada ayaa 83% ka ah qiiqa nitrogen oxide iyo 99% qiiqa ka baxa dhammaan baabuurta rakaabka ah. Tobanaan kun oo dhimasho ah oo adduunka oo dhan ah sannad kasta ayaa loo aaneeyaa NOx iyo walxaha qayb ka mid ah, sababta ugu weyn ee ay tahay matoorada naaftada. Tani waa sababta loo samaynayo sharci si loo dhimo wasakhowga baabuurtaas.
